SDF for a 2d vesica, which is a shape based on the overlap between two circles.

See Wikipedia for details. See ShaderToy for an example.

Parameters

• Radius: The radius of each circle.
• Distance: The distance between the circles. Higher values will produce thinner shapes since the circles will overlap less. Lower values will produce rounder shapes, eventually reaching a full circle when the distance is 0.

Inputs

  • Return Types: float
